SERVICING
NOTES
Replacing
chip
components
All
chip
components
should
be
connected
and
disconnect¬
ed,
using
a
tapered
soldering
iron
[temperature
of
the
iron
tip:
less
than
280°C
(536°F)],
a
pair
of
tweezers
and
braid¬
ed
wire.
Precautions
for
replacement
1.
Do
not
disconnect
the
chip
component
forcefully.
Otherwise,
the
pattern
may
peel
off.
2.
Never
re-use
a
disconnected
chip
component.
Dispose
of
all
old
chip
components.
3.
To
protect
the
chip
component,
heating
time
for
attach¬
ing
the
component
should
be
within
3
seconds.
o
Removing
chip
components
(1)
R
emoving
solder
at
electrode
Remove
the
solder
at
the
electrode,
using
a
thin
braided
wire.
Do
not
remove
the
solder
of
the
part
(chip
component)
attached
adjacent
to
the
electrode.
(2)
D
i
sconnecting
chip
components
Turn
the
tweezers
with
the
soldering
iron
alternately
applied
to
both
electrodes,
and
the
chip
component
will
be
disconnected.
Take
careful
precautions
while
disconnecting,
because
if
the
chip
component
is
force¬
fully
removed
the
land
may
peel
off.
Never
re-use
a
disconnected
chip
component.
(3)
S
moothing
the
soldered
surface
After
disconnecting
the
chip
component,
remove
the
solder
by
using
a
braided
wire
to
smooth
the
land
surface.
o
Connecting
chip
components
The
value
of
chip
components
is
not
displayed
on
the
main
body.
Take
due
precautions
to
avoid
mixing
new
chip
components
with
other
ones.
(1)
A
pplying
solder
to
land
on
one
side
Apply
a
thin
layer
of
solder
to
the
land
on
one
side
where
the
chip
component
is
to
be
connected.
Too
much
solder
may
cause
bridging.
Small
quantity
of
solder
(2)
S
peedy
soldering
Hold
the
chip
component
at
the
desired
position,
using
tweezers,
and
apply
the
soldering
iron
in
the
arrow-marked
direction.
To
protect
the
chip
compo¬
nent,
heating
time
should
be
within
3
seconds.
(3)
S
p
eedy
soldering
of
